Bringing in the users: The role for usability evaluation in eGovernment

During the last decade, various types of eGovernment evaluations have been proposed. These evaluations have primarily focused on international benchmarking using supply side metrics. Demand for eGovernment has been largely ignored. Recently, this oversight has been recognised, but research in this area is still in its infancy. This paper proposes the use of an already established usability literature from computer science. Advantages of applying usability methods to eGovernment include recognising barriers to use, identifying future development priorities and using already existing methods to assess and compare online offerings. Importantly, the inclusion of and focus on real users also fits with the wider government ideals of greater public participation and strengthening democracy.     

商业网站自制新闻面临的制度困境——试析“陆幽宫外孕”传闻中商业网站的新闻报道

2008年6月至今,一则关于足球女记者陆幽的宫外孕传闻绵延不绝。在谣言传播的中转环节中,商业网站同时充当了准专业核实者和传谣者的双重角色。这种角色的深层因素,是商业网站所面临的既可制作非时政类新闻又无采访权的制度悖论。由于这种悖论的存在,商业网站兼具专业新闻机构和民间新闻机构双重性质,其自制新闻的专业水准与传统媒体仍有相当大的差距,无法成为真正意义上的权威媒体。

Internet Reference Resources for the Life Sciences

Abstract

A virtual cornucopia of resources is available for biologists on the Internet. Many have been put up by biologists themselves; others have been mounted by organizations, government agencies or commercial businesses. In some cases, the best or only way to obtain the information is via the Internet (e.g., the gene sequence information from Genbank). Over sixty Internet biological resources are reviewed in this report in which the life sciences have been defined to include all areas of biology, agriculture and veterinary science except those which pertain to the environment or human medicine.

Scaling Up the TREC Collection

Due to the popularity of Web search engines, a large proportion of real text retrieval queries are now processed over collections measured in tens or hundreds of gigabytes. A new Very Large test Collection (VLC) has been created to support qualification, measurement and comparison of systems operating at this level and to permit the study of the properties of very large collections. The VLC is an extension of the well-known TREC collection and has been distributed under the same conditions. A simple set of efficiency and effectiveness measures have been defined to encourage comparability of reporting. The 20 gigabyte first-edition of the VLC and a representative 10% sample have been used in a special interest track of the 1997 Text Retrieval Conference (TREC-6). The unaffordable cost of obtaining complete relevance assessments over collections of this scale is avoided by concentrating on early precision and relying on the core TREC collection to support detailed effectiveness studies. Results obtained by TREC-6 VLC track participants are presented here. All groups observed a significant increase in early precision as collection size increased. Explanatory hypotheses are advanced for future empirical testing. A 100 gigabyte second edition VLC (VLC2) has recently been compiled and distributed for use in TREC-7 in 1998.

Quantifying the information needs of doctors in the UK using clinical librarians

Background and objectives: The main objective of this paper is to determine the frequency of doctors’ clinical information needs using Clinical Librarians as data collectors, focusing on the UK acute sector. Additionally, the frequency of questions followed‐up by Clinical Librarians was determined. The information needs of doctors have been investigated in other countries, particularly the USA, but not in the UK. Clinical Librarians have not been utilized as data collectors in any previous studies. Method: Clinical Librarians counted clinical questions posed by doctors in clinical settings. Results: The Clinical Librarians counted 286 questions from 655 doctors discussing 1210 patient cases. This represents approximately one question for every four patients. Conclusion: Clinical Librarians can collect data to identify the number of information needs doctors have, but this was more successful when the Clinical Librarian was experienced and an established part of the clinical team.
